  3. Finished product analysis and certification as per specified standards or customer specific standard.
  4. Utility units sample (Raw water and DM water treatment plant samples, Boiler water, Cooling water samples, Plant and Instrument Air samples and Nitrogen samples) analysis.
  5. Wastewater treatment plants and Treated Effluent samples analysis.
  6. Plant bulk Chemicals analysis.
  7. Weather monitoring.
  8. Scale and Deposit sample analysis.
  9. Investigation and failure analysis.
  10. Research and Development.

The Laboratory is accredited by National Accreditation Board for Testing Calibration (NABL) for ISO/IEC 17025-2005(General requirements for the competence of Testing and Calibration Laboratories).

Laboratory participates in Inter-Laboratory correlation program and Proficiency Testing.
The Laboratory is approved by Director General of Civil Aviation (DGCA), Center for Military Airworthiness and Certification (CEMILAC) and Directorate General of Aeronautical Quality Assurance (DGAQA), Ministry of Defence, for Aviation Turbine Fuel Testing and Certification. Laboratory is also empanelled by Karnataka State Pollution Control Board (KSPCB) for sampling and analysis of water/waste water and Air/Emissions.

The Laboratory is headed by General Manager (Quality Control and R&D) assisted by Sr. Managers (Quality Control), Managers (Quality Control), Sr. Laboratory Supervisors, Laboratory Supervisors, Chemists and General workmen.

The Laboratory is equipped with the most modern fully automatic and sophisticated instruments which are standard test method specific for accurate analysis. Testing equipments are calibrated periodically using Certified Reference Materials Traceable to National/International Standards.

Standard test methods of American Society for Testing and Materials (ASTM), Institute of Petroleum (IP), ISO (International Organisation for Standardisation), Bureau of Indian Standards (BIS), Universal Oil Products (UOP)-USA,. Shell International BV (SMS), APHA etc are adopted.
